inventory full problem

i am having some problems with my inventory, i cant place item in some of the slots and my inventory gets full easily and is damn annoying. Is everybody having the same problem with me? or any way to solve this bug.

ooo thx alot, didnt notice it was sticky

 

I re-stickied it just a moment ago, apparently someone had un-stickied it. That's why you couldn't find it (tho little searching would've done wonders, it was 2nd last topic of the first page ).
